Metal halide double perovskite semiconductors are attracting increasing attention due to their low toxicity and stability compared to lead-containing perovskite semiconductors. In this study, we focused on the fundamental physical properties of Cs₂AgInCl₆ under high pressure and investigated the effect of Bi substitution on its unique high-pressure properties. High-pressure powder X-ray diffraction measurements revealed that Bi substitution alters the mechanism of the structural phase transition accompanied by a modulated structure observed in the unsubstituted sample.
